Terminal (Program Port/Telnet) Commands
Overview
There are two types of terminal communications available on NetLinx Integrated Controllers:
Program Port - The "Program" port is a RS232 port located on the rear panel of the Master that allows
terminal communication with the Master. This type of terminal communication requires that you are
physically connected to the Master to access the configuration options and commands supported. Since this
method of terminal communication requires physical proximity as well as a physical connection to the
Master, it is the most secure form of terminal communication.
For this reason, all Security Configuration options are only available via the Program port (and cannot be
accessed via Telnet).
Teln et - This type of terminal communication can be accessed remotely, via TCP/IP. It is a less secure form
of terminal communication, since it does not require a physical connection to the Master to connect. Further,
the Telnet interface exposes information to the network (which could be intercepted by an unauthorized
network client).
Refer to the Terminal Commands section on page 99 for a listing of all commands available in a terminal session.
Note that all commands in the table are available for both Program Port and Telnet sessions, with two exceptions: "Help
Security" and "Resetadminpassword". These commands are only available via a Program Port connection.
Establishing a Terminal Connection Via the Program Port
To establish a terminal session via the Program Port, the PC COM (RS232) port on your PC must be physically
connected to the Program port on the NetLinx Master.
You will also need to know the current baud rate setting for the Master, so that you can verify that it matches the settings
on your PC.
1. In Windows, go to Start > Programs > Accessories > Communications to launch the HyperTerminal application
to open the Connection Description dialog.
2. Enter any text into the Name field and click OK. This action invokes the Connect to dialog.
3. Click the down-arrow From the Connect Using field, and select the PC COM port being used for communication by
the target Master and click OK when done.
4. From the Bits per second field, click the down-arrow and select the baud rate being used by the target Master.
5. Configure the remaining communication parameters as follows:
6. Click OK to complete the communication parameters and open a new Terminal window.
7. Type echo on to view the characters while entering commands. If that does not work, press <Enter> key on your
keyboard.
It is recommended that you make initial configurations as well as subsequent
changes via the WebConsole. Refer to the Onboard WebConsole User
Interface section on page 27.

• Parity: None
• Stop bits: 1
• Flow control: None
It is very important to execute the 'logout' command prior to disconnecting from a
Master. Simply removing the RS-232 connector from the Program Port maintains
your logged-in status until you either return to logout via a new session or reboot the
target Master.
